Was that in capital bold letters on the product package ?
In the EU, EULAS that are either too long or too hard for normal people to read are not enforceable.
Also if you bought it, its yours and you can do whatever you want with it, like resell it (and Apple is being sued for not allowing users to resell AppStore apps..).
Also, the EU is going to ship a right to repair law that will force companies to make sure their products can be repaired after support ends. And that includes software. So any mac that apple sells will need to be fully usable / repairable / etc. just for the case that apple goes out of business.
